Giorgio Giulio Clovio or Juraj Julije Klović (1498 – 5 January 1578) was a Croatian-Italian illuminator, miniaturist, and painter born in the Kingdom of Croatia, who was mostly active in Renaissance Italy.

[6] He moved to Italy at age 18 and entered the household of Cardinal Marino Grimani where he was trained as a painter.

Between 1516 and ca 1523 Clovio may have lived with Marino in the residence of the latter's uncle Cardinal Domenico Grimani in Rome.

By 1524 Clovio was at Buda, at the Hungarian court of King Louis II, for whom he painted the "Judgment of Paris" and "Lucretia".

Clovio likely returned to Rome by the end of 1538 when he is known to have met with the writer Francisco de Hollanda.

During this time he painted a miniature of Eleanor of Toledo (England, Welbeck Abbey, Private Collection).

[citation needed] Clovio illuminated the Commentary of Marino Grimani on St Paul's Epistle to the Romans.

This contains twenty-eight miniatures, mostly of Old and New Testament scenes, but with a famous double-page picture representing the Corpus Christi procession in Rome.

[22] The Vatican library has a manuscript life of Federigo III di Montefeltro, Duke of Urbino, superbly illustrated by Clovio.

A large exhibition of his works was held in 2012 in Klovićevi Dvori ("Palace of Klović"), the art gallery dedicated to him in Zagreb.

[23] According to a description written for publication by Antonfrancesco Cirni, he also designed many of the costumes for the famously elaborate wedding festivities of Ortensia Borromeo in March 1565, which were held in the Vatican and included a tournament in the Belvedere courtyard.

The costumes are carefully recorded in a series of anonymous etchings, some probably based on Clovio's design drawings.

His tomb is in the Basilica of San Pietro in Vincoli, the church containing Michelangelo's celebrated Moses.
